Conclusion on classification

alpha-Pinene multiconstituent is an organic multiconstituent substance. It is very slightly soluble in water (2.19 mg/L according to the slow-stirring method).

The short-term toxicity of alpha-pinene multiconstituent to aquatic organisms was investigated according to OECD guidelines and GLP. The following toxicity values are available for the substance and one main constituent (-)-alpha-pinene:

Fish Acute:  LC50(96h) = 0.303 mg/L for (-)-alpha-pinene (measured concentration) and LC50(96h) = 0.27 mg/L for alpha-pinene multiconstituent

Aquatic invertebrates: EC50(48 h)=  0.475 mg/L for (-)alpha-pinene (measured concentrations)

Algae: ErC50(72 h)= 0.494 mg/L for (-)-alpha-pinene (measured concentrations)

The lowest acute aquatic toxicity values based on available data ranges between 0.1 and 1.0 mg/L. There are no adequate chronic toxicity data available.

The degradation of alpha-pinene multiconstituent was investigated:

A reliable study was carried out according to OECD Guideline 301D and GLP. Under the conditions of this study, alpha-pinene multiconstituent was found readily biodegradable (68% of biodegradation on Day 28 based on oxygen consumption).

CLP Classification (Regulation (EC) No 1272/2008)

Acute aquatic hazard:

alpha-Pinene multiconstituent is classified under CLP Regulation for acute toxic hazard - Category 1. The lowest LC50value (fish) ranges between 0.1 and 1 mg/L.

Chronic aquatic hazard:

alpha-Pinene multiconstituent is classified under CLP Regulation for chronic toxic hazard - Category 1. The lowest acute LC50value (fish) ranges between 0.1 and 1 mg/L. The substance is readily biodegradable but log Kow > 4.

M-Factor: 1.

DSD Classification (Directive 67/548/EEC)

alpha-Pinene multiconstituent is classified dangerous for the environment: N; R50/53. The lowest acute LC50value (fish) ranges between 0.1 and 1 mg/L. The substance is readily biodegradable substance but log Kow > 3.
